Pulsed Electromagnetic Field is used to stimulate the human nervous system for several therapeutic purposes like pain relief and bone healing. These electrical stimulations are directly applied on the body through the cutaneous layer. Transcutaneous Electrical Nerve Stimulation (TENS) pain relief, a variant of PEMF is very popular in healthcare institutions all over the world. However, with growing...
Underlap Double Gate MOSFET with Gate Stack architectures show better performance for its enhanced immunity to short channel effects. In this work, the Underlap Double Gate MOSFET with Gate Stack having symmetric and asymmetric source drain configurations have been compared for improved subthreshold analog performance in the 32nm gate length regime. Using the data obtained from 2D numerical simulator...
It is presently established that Double Gate MOSFET has better immunity to SCE. However in underlap MOSFET structure on current reduced significantly. Graded Channel Double Gate MOSFET (GC DG MOSFET) with Gate Stack architectures show better performance for its enhanced immunity to short channel effects. In this work, low-high and high-low channel doping of the Double Gate MOSFET with Gate Stack configurations...
In this paper we have made a relative assessment of Graded channel Gate stack (GCGS) DG MOSFET structure for different high K materials by interchanging forward and reverse doping profile across the channel by using 2D Sentrausu TCAD simulator. This structure consist of gate stack (GS) engineering (high K), and non-uniformly channel engineering (GC) to overcome the short channel effects and improving...
Implementation of digital controllers in embedded environment suffers from the inherent problems associated with analog-digital signals interfacing in hard real-time, therefore, the control algorithms are invariantly subjected to approximations. This paper presents a novel technique for implementation of an efficient FPGA based digital Proportional-Integral-Derivative (PID) controller for the motion...
This paper presents the formulation of a novel block-backstepping based control algorithm to address the global stabilization problem of a flat underactuated inertia wheel system. The ideas behind the method are as follows. At first, state model of the inertia wheel system has been converted into block-strict feedback form. Then the control Lyapunov function has been designed for each cascaded dynamic...
Floating-Point addition imposes a great challenge during implementation of complex algorithm in hard real-time due to the enormous computational burden associated with repeated calculations with high precision numbers. Moreover, at the hardware level, any basic addition or subtraction circuit has to incorporate the alignment of the significands. This paper presents a novel technique to implement a...
This paper presents the formulation of a novel block-backstepping based control algorithm to address the stabilization problem for the well-known nonlinear benchmark TORA system. The ideas behind the method are as follows. At first, state model of the TORA system has been converted into block-strict feedback form. Then the control Lyapunov function has been designed for each cascaded dynamic block...
An adaptive backstepping sliding mode controller, which combines both the merits of adaptive backstepping control and sliding mode control, is proposed to address the control problem of the Furuta Pendulum in the presence of external disturbances. At first, the underactuated state model of the Furuta Pendulum has been divided into two separate subsystems. Then a pair of first layer sliding surfaces...
In this paper, a design methodology for a novel robust adaptive integral backstepping controller for the Permanent Magnet Synchronous Motor (PMSM), has been presented in a systematic manner. Backstepping is a realistic nonlinear control design algorithm based on Lyapunov design approach, as a consequence it automatically ensures the convergence of the regulated variable to zero. Adaptation schemes...
